Abstract
The utility model discloses a skeleton type optic fiber ribbon cable, which comprises a skeleton and at least one pair of signal wires, skeleton grooves are arranged on the periphery of the skeleton, optic fiber ribbons are arranged in the skeleton grooves, and the signal wires are arranged in the skeleton grooves. The utility model has the following advantages that: since the signal wires are arranged in one or more of the skeleton grooves of the optic fiber skeleton, during construction, instant calls can be made by ordinary telephones via the signal wires in the cable, so that convenient communication during construction is realized, moreover, the signal wires can be used for monitoring the safe operation state of the cable, thus realizing remote monitoring, and the signal wires also can be used as power wires.
Description
Technical field
The utility model relates to a kind of optical cable, is provided with a pair of or several to signal wire in the particularly a kind of slotted core fiber ribbon cable that has, in this optical cable one or several skeleton grooves.
Background technology
Optical fibre band optical cable has been widely used in photoelectric communication and transmission field, and it has the advantage that density of optic fibre is big, the efficient that continues is high.And slotted core fiber ribbon cable is in the optical fibre band optical cable, and a kind of optical cable of density of optic fibre maximum also is a kind of in the newfangled optical fibre band optical cable.Because this optical cable often is to be used for doing large-scale trunk line, and such circuit usually will be crossed high mountain or desert, pass through lake even ocean, therefore when carrying out the fiber cable laying construction, often run into do not have mobile phone signal, when not having telephone line, convenient communication when so just giving construction brings big difficulty, therefore might cause a large amount of wastes of human and material resources and time, and then influence the whole construction process.
Summary of the invention
In order to overcome the above-mentioned deficiency of slotted core fiber ribbon cable of the prior art, the utility model provides a kind of slotted core fiber ribbon cable that is provided with signal wire in fibre ribbon.
The utility model is that the technical scheme that its technical matters of solution is adopted is: a kind of slotted core fiber ribbon cable, comprise skeleton, described skeleton external circumferential offers skeleton grooves, in described skeleton grooves fibre ribbon is set, and comprises that also at least one pair of signal wire is arranged in the described skeleton grooves.
Further, in the above-mentioned slotted core fiber ribbon cable, be outside equipped with sheath at described skeleton, the frame center place is provided with reinforcement, the rib of skeleton is provided with the rib mark that is used to indicate the residing skeleton grooves of fibre ribbon, between skeleton and inner sheath, be provided with waterstop, between waterstop and inner sheath, be provided with and tear rope.
The beneficial effects of the utility model are, owing to be provided with a pair of signal wire in the skeleton grooves of optical fiber skeleton one or the more than one skeleton grooves, when construction, just can utilize the signal wire that has in the optical cable, carry out immediate communication with ordinary telephone set, thereby the convenient communication when realizing construction can also utilize signal wire monitoring optical cable safe operation situation, realize remote monitoring, also signal wire can be made power lead and use.
Below by the drawings and specific embodiments the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the sectional view of the utility model embodiment 1.
Among the figure: 1, rib mark, 2, skeleton, 3, fibre ribbon, 4, reinforcement, 5, skeleton grooves, 6, signal wire, 7, waterstop, 8, tear rope, 9, the bonding inner sheath of tygon, 10, the nylon inner sheath, 11, the bonding oversheath of tygon.
Embodiment
Embodiment 1, as shown in Figure 1, present embodiment is a kind of slotted core fiber ribbon cable that has only four skeleton grooves, comprise skeleton 2, skeleton 2 external circumferential offer four skeleton grooves 5, in two relative skeleton grooves 5 fibre ribbon 3 is set, fibre ribbon 3 is built up the fibre ribbon lamination side by side, comprises that also two pairs of signal wires 6 are arranged in two other relative skeleton grooves 5.In the present embodiment, only be provided with 4 skeleton grooves, in fact, size with optical cable can be provided with 3-15 skeleton grooves as required, wherein can only in a skeleton grooves, a pair of signal wire be set, signal wire more than two pairs or two pairs also can be set in two or more skeleton grooves, situation according to present use, two pairs of twisted-pair feeders of general use, be arranged in two skeleton grooves, so when needed, just can utilize the signal wire that has in the optical cable, carry out immediate communication with ordinary telephone set, thus the convenient communication when realizing construction.Can also utilize the safe operation situation of signal wire monitoring optical cable in addition, realize remote monitoring, also the affected power lead of signal wire can be used.
In the present embodiment, 2 central authorities are provided with reinforcement 4 at skeleton, and reinforcement 4 is a blue annealed wire, also can use Fiber glass rod or steel strand wires to do reinforcement as required.
